This application is a continuation application of U.S. patent application Ser. No. 16/175,739 filed on 30 Oct. 2018, entitled “PIXEL UNIT, PIXEL ARRAY, MULTIMEDIA DEVICE AND MANUFACTURING METHOD THEREOF”, which is incorporated herein by reference in its entirety.

BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention relates to a pixel unit, pixel array, multimedia device, and a manufacturing method thereof, and more specifically, the present invention relates to a pixel unit, pixel array, and multimedia device with a display medium module and a manufacturing method thereof.

2. Description of the Prior Art

With the advancement of technology and time, users are getting more demanding about visual display and voice, and require multimedia devices with the advantages of compactness, high contrast, high dynamic, high color saturation, high aperture ratio, large-sized panel, low cost and low power consumption, high quality, multi-faceted display, easy maintenance and good sound quality and other advantages of multimedia devices.

The display part of the current multimedia device can be divided into self-luminous and non-self-luminous ways to achieve the function of image display, and the liquid crystal display is the main way of non-self-luminous flat panel display device, wherein the amount of light passing through a liquid crystal medium is modulated by controlling the voltage of the upper and lower electrodes of the liquid crystal medium. The effect of color display is achieved with further employment of a color filter layer, a polarizer and some functional optical films, and backlight, etc.

Self-luminous flat panel display may be categorized into field emissive display, plasma display, electroluminescent display, organic light-emitting diode display and so on. In an organic light-emitting diode display (OLED), light-emitting polymers are deposited between an upper electrode layer and a lower electrode layer. With further employment of a conductive layer of electrons and holes, and light display is generated by adding the electric field to move the carrier, resulting in electrons and the hole carrier recombination phenomenon. In comparison, an organic light-emitting diode display device is characterized by its wide viewing angle, fast responding speed, thin panel and flexibility; further, it requires neither backlighting nor color filter and may be made large-sized.

The display panel of both LCD and OLED devices has a plate of transparent glass for a substrate, directly and sequentially forming a thin-film transistor, a lower electrode layer, a display medium layer, an upper electrode layer and others thereon. The thin-film transistor may control the voltage or current imposed on the upper electrode layer and/or the lower electrode layer to control the state of the display medium. Since it is necessary to directly and sequentially form a thin film transistor and an electrical conduction pattern on the glass substrate, whereon will be relatively compressed the effective area of pixel unit, and difficult to achieve high aperture rate of pixel unit.

Referring to FIG. 1, a top view of a known pixel. Pixel unit 1PP may serve as part of a display panel (not shown in the drawing) for displaying a pixel part of an image; generally, the pixel unit 1PP includes a glass substrate 10S, and a gate control line 11G, a data control line 12D, a thin film transistor 13T, and a pixel electrode 14PE, and a common display medium and a pixel corresponding electrode (not shown), are sequentially set up on the glass substrate 10S. The thin film transistor 13T has a gate, a source, and a drain, respectively, electrically connected to the gate control line 11G, the data control line 12D, and the pixel electrode 14PE, for controlling the state of the display medium, and adjusting the luminous flux of the pixel electrode 14PE. If the use of organic light-emitting diode (OLED) for the display medium, more thin film transistors and capacitors are needed. In addition, in order to embed the touch function, the pixel unit needs to add more signal control lines, and thus more compressed the pixel electrode (light through) the area. Furthermore, each pixel unit 1PP of the display panel is integrally formed with the same glass substrate 10S, the signal control line, the display medium, the pixel corresponding electrode, and it is not easy to replace or repair the pixel unit 1PP which is individually damaged. The larger size of the display demands the bigger range of the glass substrate needed to form the thin film transistor 13T (i.e., the array of the thin film transistor 13T has a large area), it is difficult to control the uniformity for the thin film transistor 13T of the pixel unit 1PP (Such as threshold voltage, current drive capability), the required process equipment becomes expensive, the process becomes complicated, the manufacturing time becomes longer, the cost is higher, the mass production quality and the yield control are less stable and more difficult to accomplish controlling of multi-layer display media and the manufacture of multi-facet display and repair part of the damaged display device.

The frame of display section on the existing multimedia device is refreshed every time must be combined the drive circuit element, located at the periphery of the display pixel unit 1PP, to sequentially drive the thin film transistor 13T of each pixel unit 1PP, and to update and write the content of each pixel unit 1PP, which is easy to cause power consumption issues. To combine the parts of the sound, it is usually necessary to additionally assemble the loudspeaker (speaker), resulting in a complex system with high cost and thinning more difficult.

In view of the foregoing, existing multimedia devices still have various disadvantages to overcome.

Please refer to FIG. 2A, showing a top view of a pixel unit 1PU according to a first preferred embodiment of the present invention. The pixel unit 1PU may serve as part of a multimedia device (not shown in the drawing) having a display function to display a pixel part of an image; that is, a display function device may include one or a plurality of pixel units 1PU according to the present embodiment. The pixel unit 1PU may include an active switching element 116, a display medium module 1U and other elements. The active switching element 166 may be used to control the state of the display medium module 1U to further control the amount of light passing through a display medium module 1U (or modulating the properties of light). More specific technical contents will be illustrated below.

Please refer FIG. 2A to FIG. 2F, showing cross-section views of the different constructed pixel units along the line A-A′ line of FIG. 2A. an active switching element substrate portion 166S and a transistor portion 166T formed on the active switching element substrate portion 166S. That is, the wafer portion 166T is a part of an active switching element substrate (not shown in the drawings). which may be glass, quartz, metal, metal oxide, silicon, silicon dioxide on insulator, germanium, gallium arsenide, gallium nitride, three-five compound, two-six compound, four-four compound, four-four alloy, amorphous silicon, organic flexibility, inorganic and the combination of the above (silicon wafer is used in the following illustrations), and the transistor portion 166T is formed by a series of semiconductor processes (exposure, development, etching, diffusion, deposition, ion implantation, cleaning, inspection, etc.) on the active switching element substrate. The active switching element substrate may be simultaneously formed with a plurality of the transistor parts 166T, and then the active switching element substrate may be divided into a plurality of portions (with each part including one or more transistor portions 166T) by a cutting process, and each part is the active switching element 166 described above. In addition, the active switching element 166 may further include a plurality of electric conductors 166C and a plurality of electrodes 166E formed on and/or in the upper and lower surfaces of the active element switch substrate portion 166S and/or the transistor portion 166T, The source, the gate, and the drain of the transistor portion 166T may be electrically connected to each other. The active switching element 116 may also be regarded as a chip or die.

The display medium module 1U comprises at least one pair of electrodes and a display medium 105. The pair of electrodes includes a first electrode 101PE and a second electrode 102RE, and the first electrode 101PE and the second electrode 102RE are separated from each other and may face each other. The display medium 105 is disposed between the first electrode 101PE and the second electrode 102RE. The first electrode 101PE and the second electrode 102RE may also be referred to as a pixel electrode and a pixel corresponding electrode, and may be a non-transparent, partially transparent and/or transparent electrode (e.g. formed of a metal oxide, a nano silver wire, a conductive polymer, carbon nanotubes and graphene). Electrical energy may be imposed on the first electrode 101PE and the second electrode 102RE to change the magnitude and/or the direction of the voltage, current, inductance, capacitance, electrical field, and magnetic field between the first electrode 151 and the second electrode 153 and one of the combinations thereof.

The first electrode 101PE may also be electrically connected to the active switching element 116 (e.g. via the electrode 116E of the active switching element 116 and/or another set of electrical conductors 118). The active switching element 116 may control whether electrical energy is to be imposed on the first electrode 101PE and/or the second electrode 102RE.

The display medium 105 may also be called light modulation medium. Its state may be changed via the first electrode 101PE and the second electrode 102RE to control the amount of light passing through (or modulate the properties of light). Specifically, the active switching element 116 may control the electrical energy imposed on the first electrode 101PE and/or the second electrode 102RE, causing the voltage, current and electric field and so on between the first electrode 101PE and the second electrode 102RE to change, which causes the state of the display medium 155 to change. In the case of a display medium 105 made of non-self-luminous liquid crystal, change in the state of the display medium 105 means torsional rearrangement of the liquid crystal molecules. In the case of a display medium 105 made of self-luminous organic light-emitting diode, change in the state of the display medium 105 means by the applied electric field size to move the carriers for inducing the electrons and the holes carrier recombination phenomenon, to produce light intensity and color.

The first electrode 101PE may be disposed on the first substrate 101PS, the second electrode 102RE may be disposed on the first substrate 101PS and/or the second substrate 102RS (depending on the type of the display medium 105), and the display medium 105 may be disposed between the first substrate 101PS and the second substrate 102RS (or, when the display medium module 1U comprises only one of the first substrate 157A and the second substrate 157B, the display medium 155 may be disposed on the first substrate 101PS and the second substrate 102RS). The active switching element 116 may be disposed on the first substrate 101PS and/or the second substrate 102RS, but not directly manufactured on the first substrate 101PS and/or the second substrate 102RS; that is, the active switching element 116 is independent after separately manufactured before being assembled to the first substrate 101PS and/or the second substrate 102RS. Further, the active switching element 116 may be disposed on one of the upper and lower surfaces, the inside, the groove 109GV, the perforation 109TV, and the combination of the first substrate 101PS and/or the second substrate 102RS, so that the pixel aperture ratio of the first electrode 101PE is less compressed by the active switching element 116.

The control signal line 1G, the data signal line 1D, the first electrode 101PE, and/or the second electrode 102RE may be located in the same horizontal layer or different horizontal layer of the first substrate 101PS and/or the second substrate 102RS.

In addition, when the active switching element 116 can be optimized during the manufacturing process, and used a matured process technology to have better characteristics (e.g., critical voltage, current Drive capacity and other uniformity).
